Axonal pathology of the skin in infantile neuroaxonal dystrophy.
1987
Ultrastructural studies on the skin of two patients affected by infantile neuroaxonal dystrophy (INAD) were performed to evaluate its diagnostic value and to discuss the etiology of INAD. While the majority of terminal axons around intradermal glands were dystophic consisting of tubulomembranous and tubulovesicular profiles sometimes accompanied by synaptic vesicles, there were only few dystophic axons inside intradermal nerve bundles. These observations suggest that the primary lesion of INAD is located in terminal and presynaptic axons. Therefore, terminal axons have to be investigated when a diagnostic skin biopsy is performed in INAD.
Fate of Epdxides
1982
One of the most important reactions of epoxides appears to be the covalent binding to DNA which can lead to mutagenicity and is strongly suspected to be the primary lesion ultimately leading to initiation of cancer (Miller and Miller, 1974; Oesch, 1973; Jerina and Daly, 1974; Sims and Grover, 1974; Heidelberger, 1975; Gelboin et al., 1972). This review first describes structure-activity relationships for the mutagenicity of some epoxides and then outlines some findings on the metabolic control of the concentration of such epoxides by a number of enzymes.
